Directions

  1. 1

    Make the béchamel: melt 25g of butter, add the flour and cook for 2 minutes. Gradually pour in the milk, stirring to avoid lumps. Season with salt, pepper and a pinch of nutmeg.

  2. 2

    Assemble the sandwich: spread a little béchamel on each slice of bread, add a slice of ham and a slice of cheese. Cover with a second slice of bread.

  3. 3

    Heat a buttered pan over medium heat. Grill the sandwich 3-4 minutes on each side until golden and crispy. The cheese should melt inside.

  4. 4

    Serve hot, ideally cut diagonally.

💡 Chef's Tip

For a Croque Madame, add a fried egg on top. You can also use a sandwich press for better cooking. Use good quality cheese for the best result.
